“…These results were in agreement with Boggini et al (1997), Abad et al (2004) and Lerner et al (2006). In general grain protein responded positively to increasing levels of N fertilizer in agreement with Ames et al (2003) and Abad et al (2004).…”

A subset of durum wheat Spanish landraces, previously evaluated for yield at low and high nitrogen (N) levels, was analysed for quality, protein content (P) and sodium dodecyl sulphate sedimentation (SDSS) test. The evaluation was carried out at the two N rates and in two years. The influence of prolamin alleles at the Glu-1, Glu-3, Glu-B2 and Gli-1 loci on quality parameters was also studied. The non significant Variety-by-Year or Variety-by-N interactions suggested that year and N affected all the varieties in a similar manner. Year and N effects were larger than variety effect for P, which increased with N. In contrast, variety genotype exhibited a stronger influence on SDSS test, which was not affected by year and fertilizer. Variety effects on P did not reflect the variety differences for SDSS test. A high positive influence of some prolamin alleles on quality parameters was detected, mainly for SDSS values. No correlation between yield and P was detected in the landraces adapted to low N. Based on the results of yield and quality evaluations, four landraces with high yield and high gluten strength were pre-selected for low N production.Additional key words: cereals, germplasm, gliadins, glutenins, low-N, quality breeding. ResumenEfectos del abonado N, año y alelos de prolaminas en la calidad del gluten en variedades locales españolas de trigo duro (Triticum turgidum L. ssp. turgidum) Se ha evaluado la calidad (contenido en proteína, P, y test de sedimentación con dodecil sulfato sódico, SDSS) de un grupo de variedades locales españolas cuyo rendimiento había sido estudiado previamente para alto y bajo abonado nitrogenado (N). Los parámetros de calidad se han analizado para las dos dosis de N y en dos años. También se ha estudiado la influencia en la calidad de los alelos de prolaminas de los loci Glu-1, Glu-3, Glu-B2 and Gli-1 loci. La existencia de interacciones no significativas Variedad × Año ó Variedad × N indicaron que el año y el N afectaron a todas las variedades de una forma similar. Los efectos del año y del N fueron mayores que el efecto de la variedad para P, el cual aumentaba con el nivel de N. Por el contrario, la variedad influyó más en el test SDSS que no se vio afectado por el año ni el abonado. Los efectos de las variedades en P no reflejaron las diferencias en el SDSS. Se detectó una influencia alta y positiva de algunos alelos de prolaminas en los parámetros de calidad, principalmente en los valores del SDSS. No se detectaron correlaciones entre el rendimiento y P en las variedades adaptadas a bajo N. En función de los resultados se han seleccionado cuatro variedades locales con alto rendimiento y fuerza del gluten para producción con bajo N.

“…Ames et al (2003) detected a positive influence of N on SDSS values, whereas Abad et al (2004) observed that the N effect depended on location and year. Lerner et al (2006) found significant effects of Y and fertilizer but V was the most important factor for SDSS.…”

“…An effect of foliar N fertilizer applications on grain yield has been reported in a few cases, although decreased yields following late urea spraying have been observed in other cases (Barraclough and Haynes, 1995;Peltonen et al, 1991). Other experiments on durum wheat conducted in growing areas with different climatic conditions have reported negligible effects of late-season N foliar application on GPC (Abad et al, 2004;GarridoLestache et al, 2005). Foliar application is less effective at increasing the grain N content when large amounts of N have previously been applied (Gooding and Davies, 1992).…”

ABSTRACTe foliar N application at a low rate is a strategy that could be applied by farmers in substitution to the traditional late soil application when there are restrictions on N distribution. e aim of this study was to compare the e ect of late-season N fertilization strategies on wheat (Triticum spp.) quality. Field experiments were set up in two di erent soils, in Northwest Italy. e e ect of N fertilization was evaluated on two common (T. aestivum L.) and two durum wheat (T. turgidum L. var. durum Desf.) cultivars. Late-season N was soil-applied (40 kg N ha -1 ) as ammonium nitrate at heading, or foliar sprayed (5 kg N ha -1 ) at owering, and compared with a control without N fertilization a er the vegetative growth stage. Nitrogen soil application increased grain protein content (GPC) (+15%) for both crops. is fertilization strategy led also to higher test weight (+1.4%), kernel hardness (+14%), dough strength (W) (+42%), and lower tenacity/extensibility ratio P/L (-18%) in the common wheat, and to a lower yellowberry percentage in the durum wheat (-29%). e strategy to apply a foliar N fertilizer at anthesis at a lower rate, although it has a greater cost e ectiveness, led to a less e ective bread-or pasta-making quality enhancement, with an average increase of GPC and W only in the silt loam soil by 5 and 18%, respectively. is strategy could lead to more successful increase of GPC in soils with a probable lower nitrate leaching during the vegetative stages.

“…Moreover, because intercrops are usually fertilized with a small amount of N, the risks of nitrate leaching are potentially reduced compared to a cereal which has received excessive fertilization (Abad et al 2004). Soil mineral nitrogen content measured after intercrop harvest which is an indicator of the nitrate leaching risk is 5.1±3.2 g N m −2 on average, which is slightly greater than that observed after cereal sole cropping (4.4±2.8 g N m −2 ; Fig.…”

World population is projected to reach over nine billion by the year 2050, and ensuring food security while mitigating environmental impacts represents a major agricultural challenge. Thus, higher productivity must be reached through sustainable production by taking into account climate change, resources rarefaction like phosphorus and water, and losses of fertile lands. Enhancing crop diversity is increasingly recognized as a crucial lever for sustainable agro-ecological development. Growing legumes, a major biological nitrogen source, is also a powerful option to reduce synthetic nitrogen fertilizers use and associated fossil energy consumption. Organic farming, which does not allow the use of chemical, is also regarded as one prototype to enhance the sustainability of modern agriculture while decreasing environmental impacts. Here, we review the potential advantages of eco-functional intensification in organic farming by intercropping cereal and grain legume species sown and harvested together. Our review is based on a literature analysis reinforced with integration of an original dataset of 58 field experiments conducted since 2001 in contrasted pedo-climatic European conditions in order to generalize the findings and draw up common guidelines. The major points are that intercropping lead to: (i) higher and more stable grain yield than the mean sole crops (0.33 versus 0.27 kg m −2 ), (ii) higher cereal protein concentration than in sole crop (11.1 versus 9.8 %), (iii) higher and more stable gross margin than the mean sole crops (702 versus 577€ha −1 ) and (iv) improved use of abiotic resources according to species complementarities for light interception and use of both soil mineral nitrogen and atmospheric N 2 . Intercropping is particularly suited for low-nitrogen availability systems but further mechanistic understanding is required to propose generic crop management procedures. Also, development of this practice must be achieved with the collaboration of value chain actors such as breeders to select cultivars suited to intercropping.
